A novel carbon dots (CDs) fluorescent probe was prepared by pyrolyzing the mixture of ascorbic acid (Vc) and polyethyleneimine (PEI) aqueous solution through hydrothermal method for rapid, simple and on-site detection of mercuric ion. The particle size of CDs was characterized by TEM to be 3 nm with a good dispersivity. The fluorescence of the CDs could be quenched by Hg²⁺, while remained nearly constant when exposed to other metal ions including Na⁺, K⁺, Ca²⁺, Mg²⁺, Mn²⁺, Fe³⁺, Co²⁺, Ni²⁺, Zn²⁺, Cd²⁺, Ag⁺, Ba²⁺ and Pb²⁺, implying its good selectivity. A good linear relationship between the fluorescence quenching degree (F₀-F)/F₀ of probe and Hg²⁺ concentration was obtained with correlation coefficient (R²) of 0.9878, and the detection limit (S/N=3) for Hg²⁺ was 22 nmol/L in aqueous solution. In addition, the probe was used to determine Hg²⁺ in real water samples, and the recoveries ranged from 94.0% to 105.5% in river water, tap water and mineral water samples, proving its good practical applicability for detection of Hg²⁺ in complex water samples.
